Hi Aspirant,

Hope you are doing great as per the question asked by you as in all India exams for admissions  so you need to submit central O.B.C category certificate at the time of counselling or admissions as state O.B.C category certificate will not be eligible for the same during central government exams or counselling. You need to have central category certificate to get admissions in central government colleges and state certificate for admissions in state     government colleges.

Hope you found this answer useful. Stay motivated stay positive.

All the best!
